    SPI based SSD1306

    A 7-pin OLED module offers all interfacing options like 3-wire SPI, 4-wire SPI, and I2C. The default 4-wire SPI is the fastest communication mode with the OLED. It has the following pin configuration -

    For interfacing, the module with Arduino connects the GND and VCC/VDD pins to the ground and 5V out of the Arduino, respectively. The D0, D1, RST, DC, and CS pins can be connected to any GPIO. A 6-pin module doesn't have Chip Select (CS) pin.
